The Wisen Bitbucket repository had sample code based on the RadioHead library which was useful for port numbers. This device family supports 433MHz, 868MHz & 915Mz modules. Wisen has other RFM69 based devices as well.

Thought the silk screen says RFM69 this is a prototype running an RFM95 module.

Bill of materials (Prices Sep 2018)

IoT.Net device (Beta tester will add price when available)

The device has an onboard MCP9808temperature sensor which kept the BoM really short. I have had to make some modifications to my RFM9XLoRaNetMF library as the IoT.Net device uses a different SPI port. The code for this devices and the changes will be uploaded to GitHub in the next couple of days.

The code is pretty basic, it reads a value from the light sensor, scales it, then packs the payload and sets the necessary RFM9X/SX127X LoRa module configuration, has no power conservation, advanced wireless configuration etc.
